Originally published in 1962 this book features words by F.E. Newing and Richard Bowood with classic Ladybird illustrations by J.H. Wingfield.
 
The book features experiments, things to do and explanations on how how things work with new topics on each page, such as Eyes, Shadows, Making a Pinhole Camera, The Stars, The Spectrum and so on. It's really informative and simple at the same time.
 
It's in fantastic condition apart from a little message on the front opening page.
